Abstract

A resin composition, contains: a thermoplastic polyurethane (A); a thermoplastic polyurethane (B); and an ethylene-vinyl alcohol copolymer (C), wherein an isocyanate group content (mole) in raw materials of the thermoplastic polyurethane (A) is greater than a hydroxyl group content (mole) therein, an isocyanate group content (mole) in raw materials of the thermoplastic polyurethane (B) is nearly equal to a hydroxyl group content (mole) therein, and the thermoplastic polyurethane (B) and the ethylene-vinyl alcohol copolymer (C) have a mass ratio (B/C) of from 70/30 to 99/1 and a content of the thermoplastic polyurethane (A), based on 100 parts by mass of a total of the thermoplastic polyurethane (B) and the ethylene-vinyl alcohol copolymer (C), is from 1 to 30 parts by mass. Thus, a resin composition is provided that contains thermoplastic polyurethanes and an ethylene-vinyl alcohol copolymer and is good in melt shapability.
